Inflorescences branched and fasciated. The specimens which 
are cultivated in the botanical gardens regularly produce together 
with the normal simple inflorescences compound ones. In the 
genus Bulbophyllum, so very rich in species, the occurrence of 
panicled inflorescences is not uncommon ¢fig. 12, Pl. II). 
Coelogyne pandurata Lndl. 
Habitat the East Indies. 
Coll. J. P. Moquette in. horto bogor. 
The species of Coelogyne are either terrestrial or epiphytal 
with one — or two — leaved bulbs or swollen stems. 
The pseudo-bulb of the plant represented in fig. 13 produces 
fonr instead of two leaves. : 
In order to explain the significance of this deviation, I copy 
what Mr. Smith writes to me: »Coelogyne has a long creeping 
rhizome (sympodium) which is covered with scales all over. 
After some time the top bends upward and develops to a 
pseudo-bulb of substantially one internode with two blades quite 
near to one another but still at different distances from the 
top. The scales of the rhizome are the larger the more they 
come nearer to the pseudo-bulb. The lengthening of the rhizome - 
takes place through the birth of a bud in the axil of the highest

Bulbophyllum (?) cylindraceum Lndl., but recognised it on closer examination as 
a new species, which he baptized: B. obscurum
